I cannot understand how you calculate the "d" value so I cannot complete the formula to get the code = pattern definition. So I was trying to build my own Xcel file, filling the variables (X,Y, d, el, f, g) and the LCM and HCV values but I got stuck with the "d" value. I've found one from Aussie BIM Guru but it doesn't work. Hi Eldon, I am going crazy trying to find a herringbone generator. There must be a blank line at the end of the file, and I have found that an asterisk is tolerated by Autocad and serves as a visual marker. Then the hatch pattern definition can be written (with appropriate headers):. These steps went on until the offset was 0, which gave the required value of d.Ĥ. If the offset was positive, I added Y to d and subtracted Y from the offset.
If it was, I added X to d and Y to the offset.
I then tested if the offset was negative. The offset started at -e and the length at 0. I started a reiterative process, using excel, where I had two columns d and offset. Knowing that f = X + Y, then g = (2 x LCM) - f.ģ. Then using my trusty Hatch pattern diagram (see below), e = HCF and f + g = 2 x LCM. Given a tile of length 'X' and width 'Y', I first of all factorize the numbers and then take the HCF (Highest Common Factor) and the LCM (Lowest common multiple) of X and Y.Ģ.
You may place these patterns on your system and use them in your drawings.To download these free AutoCAD hatch patterns, simply right click on the patterns you want and choose Save Link As, then place the PAT file in a path included in your AutoCAD support paths.This is what I worked out from looking at the numbers.ġ. You may not distribute these patterns in PAT form, instead refer associates to this page.You may not post them online (including web sites, ftp sites, bulletin boards, and other online services) for public downloading.Ĭoursed 3",6",4" & 5" Random Length StonesĬredit: Watson Kilbourne of CompugraphX produced the highest quality hatch patterns available anywhere.Watson has donated these hatch patterns to the AutoCAD community. Any hatch pattern you find should work with any previous or future version of AutoCAD! The good news is that the hatch pattern format hasn't changed since it was first introduced years ago. There has been a change in behavior in AutoCAD 2005 regarding the object snaps on its geometry. In previous releases osnaps would honor hatches, in 2005 they are ignored by default.
